Yini emthambekeni kuphesenteji, futhi kanjani ukuhumusha ku-degree

Lapho ekhuluma ngokuphela phezulu ophahleni, ukuthi igama elithi "Ukuthambekela" kusho engela ukuthambekela igobolondo ophahleni kuya ovundlile. Ngo geodesy, lokhu ipharamitha yisikali sokuthi lo steepness emthambekeni, futhi imibhalo phrojekthi degree of ukuphambuka izakhi ngokuqondile kusukela imigqa isizinda. Slope ngokwamazinga akakubangeli izinkinga noma ubani, kodwa nokuchema iphesenti ngezinye izikhathi kubangela ukudideka. Sekuyisikhathi ukubhekana nalokhu yokukala ukuze sicacise ukuthi hlobo luni kuba, futhi uma kudingeka, ulithumele nezinye amayunithi ngaphandle nobunzima, isibonelo kule degrees efanayo.

Ukubalwa emthambekeni e amaphesenti

Zama unxantathu wesokudla-angled ABC, elele omunye imilenze yaso AB. Umlenze kwelanga yesibili izodluliselwa thwi phezulu bese lwakha hypotenuse AC cathetus nge engela aphansi. Manje thina kufanele ucabange kancane kancane bese trigonometry ukuze bala yayo tangent, okuyinto nje ephawula emthambekeni eyakheke yi hypotenuse unxantathu ne engezansi umlenze. Ake sithi umlenze AB = 100 mm ukuphakama ilanga = 36,4 mm. Khona-ke tangent yethu engela kuyoba ulingana 0,364, okuhambelana amatafula 20˚. Kungani-ke, kungaba ulingana emthambekeni njengoba amaphesenti? Ukuhumusha ukubaluleka etholwe kulezi amayunithi, singamane nande ukubaluleka tangent 100 futhi uthole 36,4%.

Kanjani ukuqonda engela ukuthambekela iphesenti?

Uma uphawu traffic ikhombisa 12%, kusho ukuthi zonke ikhilomitha we ukwenyuka nokwehla endleleni lizokwenyuka (Yehla) ngamamitha angu-120. Ukuze ukuguqula iphesenti Inani ngama-degree, kubalulekile ukuze nje Balisisa-arctangent ukubaluleka nokudluliselwa ke kusukela radian abe amadigri evamile uma kunesidingo. Kuyefana nasendleleni imidwebo ukwakhiwa. Uma, ukwenza isibonelo, uthi engela emthambekeni e amaphesenti 1, kusho ukuthi isilinganiso umlenze omunye komunye ilingana 0.01.

Kunganjani ngokwamazinga?

Abaningi impela abanesifiso sokwazi: "Kungani ukusebenzisa emthambekeni enentshisekelo?" Yebo, kungani ungamenzeli ngezinga elithile. Iqiniso lokuthi kukhona njalo ezinye iphutha zonke izilinganiso. Uma imibhalo project kuyoba degrees osetshenziswayo, ngaso nakanjani babe nezinkinga nge ukufakwa. Thola okungenani okufanayo amapayipi ipayipi. Isiphambeko a degrees ezimbalwa ngesikhathi ubude 4-5 amamitha kungathatha wakhe impela isikhundla ezahlukene kusukela ohlangothini lokunene. Ngakho-ke, ngo-imiyalelo, isiqondiso kanye nezincwadi iphrojekthi amaphesenti ngokuvamile asetshenziselwa.

Isicelo practice

Ake sithi ukuthi Project kuhlanganisa ukwakhiwa ezweni endlini kudivayisi bamisa ophahleni. Ufuna hlola umyela kuphesenteji kanye degrees, uba kusaziwa ukuthi ukuphakama yokhalo kuyinto 3,45 m eyaziwa futhi ububanzi ikhaya esizayo 10 amamitha. Njengoba uphahla phambi kuyinto unxantathu equilateral, kungashiwo ihlukaniswe onxantathu ezimbili kwesokudla lapho ukuphakama yokhalo, uyobe uzipha esinye imilenze. Umlenze wesibili esimthola sokuhlukanisa ngesigamu kobubanzi bendlu. SesineHholo yonke idatha ezidingekayo sokubalwa ukubaluleka emthambekeni. We ^{ukuthola: atan -1 (0.345) ≈ 19˚} . Ngakho, umthambeka singamaphesenti angu 34,5. Lokho esikwenzayo ngawe? Okokuqala, singaqhathanisa lesi silinganiso ne nemingcele batusa ochwepheshe, futhi okwesibili, ukuhlola nezidingo SNIP lapho ekhetha izinto ukufulela. Consulting lwemibhalo, ungathola ukuthi laying Tile zemvelo ukuthambekela ezingeni sincane kakhulu (ezingeni obuncane degrees 33), kodwa kophahla enjalo akesabi ipheshulwa enamandla womoya.
